Founded in 2011 and headquartered in Clermont-Ferrand, Carbios has pioneered industrial enzymes capable of depolymerizing post‐consumer PET into its original monomers. These monomers can then be purified and repolymerized into virgin‐quality PET, offering a circular solution to plastic waste. The company’s core technology relies on proprietary engineered hydrolase enzymes that accelerate the breakdown of polyethylene terephthalate under mild conditions. Carbios has advanced its platform through laboratory research and pilot‐scale demonstrations, and it is now focused on scaling up to industrial production. In 2021, Carbios commissioned a semi‐industrial demonstration plant in France to validate the performance and economics of its enzymatic recycling process. Carbios has entered into collaboration and licensing agreements with leading global companies in the food, beverage, and textile sectors to bring its biorecycling solutions to market. Strategic partnerships with enzyme producers and consumer-goods manufacturers aim to integrate Carbios’ technology into existing recycling infrastructure and to support adoption in Europe, North America, and Asia. The company’s approach addresses growing regulatory and consumer demands for sustainable packaging alternatives. Carbios is publicly traded on Euronext Paris and is available over the counter in the U.S. under the ticker COOSF. Led by a team of biotechnology and industrial‐process experts, the company continues to refine its enzymatic platforms and advance toward commercial licensing. Its mission is to create a fully circular economy for PET materials by deploying scalable, low-energy recycling processes worldwide.AI Generated. May Contain Errors.
